Openvz – Workshop

OpenVZ (Open Virtuozzo) is an operating system-level virtualization technology based on the Linux kernel and operating system. OpenVZ allows a physical server to run multiple isolated operating system instances, called containers, virtual private servers (VPSs), or virtual environments (VEs). OpenVZ is similar to FreeBSD jails and Solaris Containers.

OpenVZ is not true virtualization but really containerization like FreeBSD jails. Technologies like VMWare and Xen are more flexible in that they virtualize the entire machine and can run multiple operating systems and different kernel versions. OpenVZ uses a single patched Linux kernel and therefore can run only Linux, all containers share the same architecture and kernel version. However, as it does not have the overhead of a true hypervisor, it is very fast and efficient. The disadvantage with this approach is the single kernel. All guests must function with the same kernel version that the host uses.

The advantages, however, are that memory allocation is soft in that memory not used in one virtual environment can be used by others or for disk caching. OpenVZ uses a common file system so each virtual environment is just a directory of files that is isolated using chroot, newer versions of OpenVZ also allow the container to have its own file system. Thus a virtual machine can be cloned by just copying the files in one directory to another and creating a config file for the virtual machine and starting it.

Concluding Session

People were requested to handle small technical discussions for the next meeting.

Thanks to all the attendees for coming and they are requested to put their feedback on the mailing list so that we can improve future meetings

Indian Libre User Group is spreading Free Software awareness in society through its regular monthly meetings ( 4th Sunday of every month ), conducted since 1997. ILUG Cochin (www.ilug-cochin.org) is holding its regular meeting for this month on Sunday, 23rd March 2014.

We start of with our regular discussion on the concepts and philosophy of the Free Software Movement and related topics.

2. Agenda : Openvz(Proposed Workshop)

Container based Virtualisation, creating multiple secure GNU/Linux containers. Please confirm immediately and bring your laptops for software installation,before the meeting preferably before the meeting on weekdays or on saturday (with prior time confirmation towards the afternoon-evening). Any change would be notified before the meeting.

3. Technical Discussions

Attendees will discuss and/or present topics of interest. They will share their knowledge by handling small sessions to make up the Technical Session part of the Meeting.

4. Q&A Session

This would be used to answer doubts that users have concerning Free Software.

We look forward to your participation for this exciting meeting. Hope to meet you all on Sunday.

Btrfs (B-tree file system, variously pronounced: “Butter F S”, “Better F S”,”B-tree F S”,or simply “Bee Tee Arr Eff Ess”) is a GPL-licensed experimental copy-on-write file system for Linux. Development began at Oracle Corporation in 2007. It is still in heavy development and marked as unstable, especially since when the filesystem becomes full, no-space conditions arise which might make it challenging to delete files.

Btrfs is intended to address the lack of pooling, snapshots, checksums, and integral multi-device spanning in Linux file systems, these features being crucial as Linux use scales upward into the larger storage configurations common in enterprise.Chris Mason, the principal Btrfs author, has stated that its goal was “to let Linux scale for the storage that will be available. Scaling is not just about addressing the storage but also means being able to administer and to manage it with a clean interface that lets people see what’s being used and makes it more reliable.

Wireless security is the prevention of unauthorized access or damage to computers using wireless networks. The most common types of wireless security are Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA). WEP is a notoriously weak security standard. The password it uses can often be cracked in a few minutes with a basic laptop computer and widely available software tools. WEP is an old IEEE 802.11 standard from 1999 which was outdated in 2003 by WPA or Wi-Fi Protected Access. WPA was a quick alternative to improve security over WEP. The current standard is WPA2; some hardware cannot support WPA2 without firmware upgrade or replacement. WPA2 uses an encryption device which encrypts the network with a 256 bit key; the longer key length improves security over WEP.
